To be fair, Accor has a list of lounges that Platinums have access to and that one is not included..

While true, this is in my opinion one of the biggest issues with Accor - the lack of consistency and the extent to which hotels are allowed to make exceptions to the rules. If lounge access is a Platinum benefit, it is absolutely unreasonable to expect members to check a constantly changing list of hotels where that benefit does or does not apply.
